Abstract[EN] The invention relates to a compound having general formula (I) or one of the salts thereof, in which: R1 represents CH2OH o COOH and R2 represents a linear or branched hydrocarbon chain C4-C22, wherein the hydrocarbon chain can optionally have one or more unsaturations selected independently from alkenyl- or alkynyl-type unsaturations, provided that, when R1 represents CH2OH and R2 represents a linear or branched hydrocarbon chain, optionally with one or more alkenyl unsaturations, the length of the hydrocarbon chain is C4-C12. The invention also relates to the production method thereof and to the use of same as a surfactant and oxidising agent, in particular as part of a composition in the form of an emulsion.
[ES] Compuesto de fórmula (1) o una de sus sales, donde: R¡ representa a CH20H o COOH y R2 representa una cadena hidrocarbonada C4-C22 lineal o ramificada, donde la cadena hidrocarbonada puede opcionalmente presentar una o varias insaturaciones elegidas independientemente entre insaturaciones de tipo alquenilo o alquinilo; siempre que, cuando R¡ representa CH20H y R2 representa una cadena hidro carbonada lineal o ramificada, opcionalmente con una o varias insaturaciones alquenilo, la longitud de la cadena hidrocarbonada es C4-C12 • Su procedimiento de obtención y su uso como surfactante y oxidante, en particular como parte de una composición en forma de emulsión.
